A Montecito mansion known as California’s Palace of Versailles is hitting the market for a colossal $29.5 million.

The chateau-style estate — complete with its own bank vault and secret tunnel — is in the same neighborhood as the likes of Oprah, Prince Harry and Meghan Markle, Gwyneth Paltrow and Ellen Degeneres.

The estate, made up of five bedrooms and 10 bathrooms, spans 12,000 square feet. It’s located near Santa Monica, in the Birnam Wood community of Montecito.

Situated on nearly 2 acres, the home comes with rare and luxurious features including imported French marble countertops for the kitchen, gold bathroom fixtures and historic chandeliers, according to Jam Press.

The marble is said to be worth millions of dollars alone, with the brickwork hailing from Italy.

On the lower level of the estate are closets which have woodwork and craftsmanship inspired by the film “Titanic.”

Perhaps the most jaw-dropping features include a Swiss bank vault in the butler’s pantry to protect any valuable kitchenware, and an underground tunnel leading to a cellar that can accommodate 200 bottles of wine.

Amenities of the estate include a full-service wet bar, a gym, sauna, steam room, swimming pool, putting green and plans to create a movie theater, finished off with optimal security.

Exterior features of the gated home include a 1,000-year-old Carrara fountain placed in the manicured garden, which holds patented roses exclusive to the property.

Berkshire Hathaway Luxury Collection holds the listing.
